PECTORAL PLANE BLOCK COMPAIRED TO ERECTOR SPINAE PLANE BLOCK IN MULTIMODAL ANALGESIA FOR MASTECTOMY PATIENTS IN SOUTH ASIAN POPULATION -A PROSPECTIVE RANDOMISED CONTROL TRIAL

Overview

This prospective randomized controlled trial was conducted at the Department of Anesthesia, Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH\&RC), Lahore. The sample size was calculated based on a previous study by Gad M. (2019) on patients undergoing modified radical mastectomy , where the mean morphine consumption in first 24 hours post operatively was reported as 16.7 ± 7.21 mg in the erector spinae plane (ESP) block group and 10.7 ± 3.12 mg in the pectoral plane block (PECS) group. Using the formula for comparison of two means with unequal standard deviations, and assuming a 90% power, 95% confidence interval, and a 10% dropout rate, the required sample size was determined to be 42 patients, with 21 patients in each group.
